Last Meal of History's Most Famous 'Bog Body' Hints at Human Sacrifice
That's similar to what scientists found in the early 1950s, when the body was first unearthed in what is now modern Denmark. But unlike past analyses, this one has also noticed a few new ingredients, like the fatty proteins of fish as well as remnants of threshing waste, which comes from separating grain.
That's an intriguing discovery, as a recent analysis of another bog body, known as the Grauballe Man, has also turned up a surprisingly large quantity of threshing waste no noticed before.

I've always though this was a ritual killing because of the way the body was arranged. Criminals were bludgeoned, stabbed, and/or garroted and dumped face down, often with willow sticks making sure they wouldn't come back up. Tollund Man was arranged on his side in a fetal position, as though he was asleep.
I do rather cut to the chase on the threshing waste, though. It was most likely an indication of a very poor harvest, the waste added into the porridge to supply bulk to starving people. It would also explain his death and the reverent way his body was arranged.
